I bought the 18v combo hammer drill/driver and impact from home depot. They are pretty good. When using the drill with a big hole saw or wood bits in high speed it will cut power to protect the motor from overamping if the motor stalls, its kinda annoying. It dosent do that in low speed. The impact is good, lots of power. The LED light only comes on while the trigger is pulled. My last makita the light would stay on for a few seconds after the trigger was pulled, it makes it a little harder to work in the dark.
